How to improve Android battery life

One of the biggest areas of opportunity to optimize your battery is to optimize how your phone screen shows things. This not only helps with your battery life, but could dramatically improve your experience with the phone (specifically with Optimization 2).

Access Display Settings

Go to Android Settings
Tap on Display

Optimization 1: Switch to Dark Mode

Switching to a Dark Mode, means that all of the user interface elements will be shown in black, gray or much darker tones. For the android users who have newer (more expensive) phones that use an OLED technology for their screens, this means that the darker areas of the screen will use less energy to display. That will contribute to improving your battery life.

If you don’t have an OLED display, this would make a negligible difference. Not sure what type of display your phone has? Look up the display specifications on your phone box or on its web site.

In the abovementioned Display Settings, toggle on Dark Mode. It might look different on your flavor of Android, but the general idea is the same - Dark Mode.

Optimization 2:

Adaptive Brightness

Your phone’s light sensor, which is usually located by the audio output (where you place your ear to talk), measures the intensity of the light around you. If it’s bright, it will crank up the phone screen brightness to help you see better. If it’s darker, it will reduce your screen brightness to save your battery life and your eyes from the bright display light. It is called Adaptive brightness.

To enable the Adaptive Brightness, while you are in the display settings, turn on the toggle for Adaptive Brightness. That’s all you need to do. Your phone will take care of the rest automatically.

Optimization 3: Change Screen Resolution

Phones nowadays have very sharp screens. In order to make the screens sharp, the manufacturers cram millions of pixels into them (think of them as tiny light bulbs). In order to show you the picture on the screen, these pixels need to flicker 60 times every second.

As you can guess, the more pixels your phone shows, the more electricity it takes to power the internal circuitry that controls these pixels. If you tell your phone to show less pixels (by reducing the screen resolution), that will lower the energy requirements of your phone’s circuitry and further improve your battery life. This, as you have guessed, could come at an expense of a slightly less sharp image.

However, for many users it is either a worthy compromise or a non-issue at all. The screen resolutions on modern phones is so high, that it is sometimes even difficult to tell the difference looking at your phone from a half a foot away.

To adjust your screen resolution (reduce it), in your Display Settings tap on Screen Resolution and set one of the lower options.

You can usually tell lower resolutions apart from higher ones by looking at the resolution numbers, or by simply sliding down the slider to the left (on some phones).

Make sure to tap Apply to apply the changes.

These 3 optimizations should help you improve your battery life. Please feel free to comment and let me know how well this worked for you. Also, don’t hesitate to share with friends or on social media.
